Title: Improvements in cutting-speed indicators for lathes and other machine-tools
IPC: B23Q17/00
Filed: 1943-10-04
Abstract: 569,828. Cutting-speed indicators. BOCK, S. J. KERR-, and COOPER-STEWART ENGINEERING CO., Ltd. Oct. 4, 1943, No. 16232. [Class 83 (iii)] In a cutting speed indicator for lathes or other machine tools, the drive is in synchronism with the work rotation and actuates a pointer g reading against a number of concentric scales m ... r, each scale being appropriate to a different work diameter and the permissible upper and lower surface speeds being indicated on the scales by curved lines s, t. The pointer g is actuated by a magnetic or other tachometer driven by a flexible shaft &c. projecting from the back of its casing and the device may also include revolution counters c, d driven by a flexible shaft, ratchet, &c. e from a part of the machine which completes its movement after each cycle of operations, such as the turret slide or cam shaft, thus indicating the number of articles produced. The counter c indicates total production and the counter d has 'a trip which may be re-set periodically, the drive being by gears y, z, whereof the latter is displaceable axially by a removable key to re-set the counter d. The scales may be marked on interchangeable dials k of metal, plastics &c., each being marked to correspond to a different work material and cutting tool and being fitted in a slideway h of the indicator casing covered by a dust cap i. A slot v in the dials clears the pointer spindle and slots u enable the counters c, d to. be observed. The outer dial scale l indicates r.p.m. of the work and the curved lines s, t enable the pointer to interpolate work diameters between those indicated by the scales m ... r. The dials also contain information showing the work material and type of tool for which they are appropriate, and the maximum and minimum permissible cutting speeds.

Title: Improvements in or relating to the conversion of dolomite into magnesium hydroxide
IPC: C01F5/22
Filed: 1959-05-12
Abstract: Slaked, calcined dolomite is converted into magnesium hydroxide by mixing the dolomite with an aqueous brine containing from 0,15 to 1,0 gram molecule per litre of MgCl2 to cause flocculation of Mg(OH)2 and to convert the Ca(OH)2 of the dolomite into CaCl2, and maintaining a concentration of MgCl2 in the brine of at least 0,005 gram molecule per litre during the conversion.  The precipitate is washed with water having a MgCl2 concentration of at least 0,005 gram molecule per litre, or containing a flocculant, e.g. starch.  In Examples 1 and 2 slaked calcined dolomite is reacted with brines containing NaCl and MgCl2, and the Mg(OH)2 washed and filtered.  In Example 3 slaked calcined dolomite grains are soaked in MgCl2 brine and then transferred from one vessel to another in a series of vessels in counterflow to brine of increasing MgCl2 concentration, allowed to react for increasing periods of time, and then washed by transfer through a series of vessels in counterflow to water.  Specification 881,813 is referred to.

Abstract: 708,894. Hand grips for vehicles. AUSTER, Ltd., and SMALL, W. W. March 30, 1953 [June 28, 1952], No. 16340/52. Class 103(4) A hand grip for use in passenger vehicles of the kind which is hinged or pivoted to depend from the roof of the vehicle, is provided with a pair of springs: disposed one on each side of the pivoted end of the hand grip whereby one or both of the springs moves the hand grip into a parking position when it is released from use: In the construction shown, the hand grip comprises a stirrup portion 1 fixed to a shank 3 carrying a pivot-pin 4 which is rotatably mounted in apertures in a forked bracket 6 fixed to the roof of a vehicle. The ends of the pivot-pin 4 are reduced in diameter and are slotted each to receive one end of a flat volute spring 8, the other end being anchored to a pin 12 carried by a cover plate 10. The springs are wound in the same direc - tion so that they both tend to keep the hand-grip in the parking position. Spring- pressed plungers 13 may be provided for engagement on nobs 16 in the forked sides of the bracket 6, so that they give slight resistance to movement from the parking position. In a modification the volute springs are wound in opposite directions so that either one or the other is effective to return the hand grip to the parking position after use.

Title: Electro-metallurgical process for manufacture of ductile bodies of high-fuzing metals and alloys of same
IPC: C21D11/00
Filed: 1920-06-17
Abstract: 168,697. Aoyagi, E. June 17, 1920. Dry processes of refining tungsten, molybdenum, &c.-A process for the manufacture of ductile rods from high-fuzing metals such as tungsten, molybdenum, &c., or alloys of the same, consists in heating rods made of the said substances hung vertically in a vessel containing neutral or reducing gas at high pressure by the passage of an electric current or by an electric furnace, bringing them to a nearly molten state and then using the elongation of the rods to stop automatically the heating' current supplied to the rods or furnace. Two rods of tungsten 1 and 2 are placed vertically in a vessel 10 lined with refractory material 10<1> having openings 17 and 18 provided with cocks for the inlet and outlet of the inert gas, the lower ends 20 of the rods 1, 2 being connected bv a horizontal tungsten rod 3. The upper ends of the rods fit into. two electrodes 4, 5 which are fixed to two other electrodes 8, 9 having water jackets 6, 7 joined bv a pipe 23 of insulating material, these electiodes 8, 9 being insulated from one another and the vessel 10 by insulating-pieces 21, 22. The heating current is supplied to these electrodes 8, 9 through lines 12" of low resistance upon closing a switch 12, and the elongation of the rods 1 and 2 causes contact between the rod 3 and an adjustable insulated electrode 12<1> which allows the current to pass through a local circuit comprising a low-resistance line 15<1>, a switch 14 normally closed, and a trip coil 16 which then opens the main switch 12. When the rods are heated by an electric furnace, the elongation of the rods make contact as before to close a local circuit which may operate means to cut off the main heating current. If the material of the rods contains impurities, the rods may be heated initially under a reduced pressure to eliminate the impurities by vaporization and later the high pressure applied.

Title: Improved manufacture of plates from asbestos or fibro-cement
IPC: B28B1/42
Filed: 1929-05-28
Abstract: 329,850. Bindschedler, R. May 28, 1929. Making slabs.-A process for making asbestos cement or fibro-cement plates consists in depositing the cement and the abestos on the surface of a rotating drum in successive layers and not as a mixture, as usual, so that the plates are laminated. In this way, it is possible to make a plate, shown in section in Fig. 2, having a thick core 1 of cement faced with thinner layers 2 of asbestos which are covered by layers 3 of cement. Apparatus for making the plates comprises an endless belt C, Fig. 1, which makes contact with rotary sieves B that dip into troughs A containing cement. The belt becomes charged with cement and applies it to the surface of a rotary drum until the desired thickness is built up. Cards I of known type are driven by the belt and feed asbestos or other fibre on to the upper run of the belt C. Thus asbestos and cement can be applied in layers to the surface of the drum E, and when sufficient thickness has been obtained, the material is cut and removed from the drum and spread out to form a plate.
